contrast sensitivity meant you aged quicker or slower?
I've noticed really old people are thin and have good teeth, taking care of dental issues seems to be good.
No doubt thin and wirey appear to help long lives. One thing each individual can do is get their Lp(a) checked. Lp(a) is a component of cholesterol and it is a component that Linus Pauling believed is the one part of cholesterol that contributes to heart disease. Supporting that is a study of about 4000 older men in NEJM. Those with Lp(a) levels in the highest quintile(top 20%) had a risk of death from all causes that was %300 greater than people with Lp(a) in the lowest %20. That is quite significant. This is a test you must ask for, it is not part of the normal cholesterol screening. Dangerous levels in the study were 30 and over while under 22 was good. The good news is that it can be reduced by binding it with Lysine according to Pauling.
Most very elderly people are thin because they don't eat much, have little muscle mass and are not really absorbing much of what they do eat. To ascribe longevity to "thin" is akin to ascribing old age to white hair and baldness. This article is about aging at the cellular level. FPS.
